Well, that didn't take long. I'm posting a simple script that captures the
system time output of the time command to a variable in case anyone else
has spent a good bit of time trying to get this to work, like me. This works
even if /bin/sh is linked to /bin/dash, so my assumption appears to have
been correct.
$cat gettime.sh
#!/bin/sh
##################################################
# Script CONSTANTS: #
##################################################
BLOCKSIZE=10000
INFILE="/dev/urandom"
OUTFILE="/tmp/random.$RANDOM"
TIME_CMD="/usr/bin/time"
TIME_FORMAT="%S"
##################################################
# Exit status codes: #
##################################################
E_BAD_CLEANUP=65
SUCCESS=0
##################################################
# Script Variables: #
##################################################
blockcount=1000
totaltime=$(/usr/bin/time -f $TIME_FORMAT dd if=$INFILE of=$OUTFILE
bs=$BLOCKSIZE \
count=$blockcount status=noxfer 2>&1 | sed -e "1,2d")
echo "Total time: $totaltime"
# CLEAN-UP:
if [ -e $OUTFILE ]
then
rm -f $OUTFILE || exit $E_BAD_CLEANUP
fi
exit $SUCCESS
Script output:
$ sh gettime.sh
Total time: 0.74
PS The reason I started the original post was because I noticed
OUTFILE was being defined as random. instead of random.####
so I wanted to track that down first.
